The adoption of latest integrated COB of LEDs effectively improves color uniformity and luminous efficiency, more red and blue light, less white light. Best solution of heat dissipation system: sunflower radiator effectively improves the heat-sinking effect, and prolong lifespan of led grow light. Isolated power source: cut the too strong current and protect chips. Conveniently Cross-connection of Products with Daisy-chain power cord design. Flexible use and energy efficiency: Adopts new combination of power supplies, two sets of power group control in one grow light makes it easier to allocate light units for special requirements of plants.
